Definitions

  • the invention relates to a securing device for the transport and installation of a measuring device for determining the position of two relatively movable components according to the preamble of patent claim 1.
  • Such a securing device is used, in the transport and assembly of a measuring device, a longitudinal measuring graduation, a support body for the measuring graduation, a scanning the measuring graduation and guided at a defined distance from the measuring graduation scanning and a mounting base for attaching the scanner to a of the two mutually movable components, the scanning device in a defined position (desired position) set relative to the carrier body of the measuring device.
  • the securing device comprises a body which is longitudinally displaceable along a guideway of the carrier body and which can be secured on the mounting foot on the one hand and on the carrier body on the other hand in order to be able to hold the mounting foot in a predefinable desired position relative to the carrier body.
  • the two components that are movable relative to one another may in particular be the carriage and the associated bed of a machine tool.
  • the carrier body with the measuring graduation on the one hand and the mounting foot with the scanning device on the other hand attached to each one of these two components.
  • a safety device of the aforementioned type which has two along the extension direction of the measuring graduation spaced-apart base body, which are arranged on one end face of the mounting foot and connected to each other via a guide element.
  • the two basic bodies can be fixed in each case by clamping forces on the carrier body of the measuring graduation, so that the assembly foot can be positioned between the two basic bodies at a defined position of the carrier body of the measuring graduation. In this case, a secure support on both sides of the mounting foot is made possible in its desired position.
  • the invention is based on the problem of further improving a safety device of the type mentioned in the introduction, in particular with regard to a simplified positioning of the mounting foot on the carrier body by means of the safety device.
  • the solution according to the invention allows a connection of the securing device in only one operation and in particular by actuation of the securing device at only one point, namely at its base body with the mounting foot on two along the extension direction of the measuring graduation or in the direction of displacement of the main body spaced apart locations of the mounting foot, preferably in the vicinity of the two end faces of the mounting foot.
  • the extension is integrally formed on the base body.
  • the body and extension of the securing device can also be formed by separate, interconnected assemblies.
  • the connecting means are in turn preferably integrally formed on the extension and provided for insertion into an associated connection point of the mounting foot, in particular for forming a (positive) locking or plug connection by moving the body along the guide path of the carrier body provided therefor.
  • the extension is preferably angled in the region of the connecting means such that the connecting means can slide over a ramp provided at the connection point of the mounting foot.
  • guide means are provided on the extension, by means of which the extension along an associated guide means of the carrier body, in particular along the same guide track as the base body of the securing device, in the extension direction of the measuring graduation is displaceable.
  • the guide means close in the extension direction of the extension directly to the connecting means and are advantageously formed by two along that extension direction spaced guide portions. This makes it possible to achieve that, upon engagement of the connecting means of the extension in the associated connection point of the mounting foot, in particular in a simultaneous driving over a ramp of the mounting foot, by lifting, ie by a movement transverse to the direction of displacement of the base body and the extension, the extension to the support body is clamped by the guide means of the extension are pressed against the associated guide means of the carrier body.
  • the extension has two substantially mutually parallel legs, which are each provided with connecting means and guide means.
  • the main body of the securing device itself is designed such that it can be fixed to the mounting foot by moving along the guideway of the carrier body by means of a plug-in and / or latching connection form-fitting manner.
  • the main body may have plug elements which can be inserted into an associated plug region of the mounting foot.
  • These connector elements are preferably formed by a respective projection, in particular in the form of a pressing nose, of the base body, which can be inserted into a recess of the mounting foot.
  • the base body may have a latching element in the form of an elastic latching lever, which can be latched into a latching position of the mounting foot designed as a latching opening.
  • the main body on guide means which are displaceable along the guide rail of the carrier body in the extension direction of the measuring graduation and can be clamped thereto by means of an actuating element.
  • the actuating element is preferably rotatable and can be designed, for example, as a knurled screw or knurled nut. This acts in its operation on a (separate) clamping element, which in turn braces the guide means against the guide rail of the support body and thereby produces the clamping connection.
  • the actuating element With the actuating element, three different states of the clamping element can be adjusted, wherein in one state of the clamping element, the securing device can be removed from the carrier body, in a further state of the clamping element, the securing device along the guide track is displaceable and in the third state of the clamping element, the securing device is clamped fixed to the carrier body. Rest stops can be provided on the actuating element, by means of which the actuating element can be locked in the various positions which correspond to the three aforementioned states of the clamping element. Alternatively, the positions of the actuating element corresponding to the three aforementioned states of the clamping element may be marked by markings.
  • the actuating element to form a backstop on blocking means which prevent by interaction with an associated locking element of the body that the actuating element is inadvertently transferred to a state in which the clamping piece would be released from the securing device.

  • connection point is provided on the mounting foot into which the connecting means of the extension automatically engage when the base body is fixed (by displacement along the guide track of the carrier body) to the mounting foot. This is preferably done in such a way that when fixing the body on the mounting foot of the extension snaps with its connecting means in the associated connection point of the mounting foot and thereby produces a positive and optionally complementary frictional connection.
  • the junction of the mounting foot has a ramp by means of which the extension is raised in the region of its connecting means, so that the guide means of the extension are pressed against a stop of the associated guide means of the support body and a clamping connection between extension and support body is made.
  • a ramp is generally considered to be an element provided at the connection point of the mounting foot which causes a displacement or deformation of the connecting means of the extension transversely to its direction of displacement on the guideway or transversely to the extension direction of the measuring graduation, irrespective of the geometric configuration of the ramp , This does not necessarily have to be designed in the manner of an inclined plane or the like. It is sufficient that the ramp can cause a movement of the connecting means (possibly by elastic deformation of the connecting means) transversely to the aforementioned extension or displacement direction.
  • this has an insertion phase.
  • the extension comprises two legs extending parallel to one another, each having connecting and guiding means, two connecting points (arranged juxtaposed transversely to the guide track), which are each associated with one of the two legs of the extension, are provided on the mounting foot.
